WebLCA is the result of dispersion of the chief ray. Thus, when a lens exhibits LCA, light is affected very similarly to light traveling through a dispersive prism (figure 1.5). Imagining the prism in figure 1.5 is the tip of a lens shows us how the phenomenon occurs in a lens like one from figure 1.4. Webby the clear aperture on the rear surface of the third lens.

The ray in geometrical optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. The simplifying assumptions of geometrical optics include that light rays: propagate in straight-line paths as they travel in a homogeneous medium. See more In optics, a ray is an idealized geometrical model of light or other electromagnetic radiation, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of See more There are many special rays that are used in optical modelling to analyze an optical system. These are defined and described below, grouped by the type of system they are used to model. See more A light ray is a line (straight or curved) that is perpendicular to the light's wavefronts; its tangent is collinear with the wave vector.

Refraction effects come from the curvature of the lens. At the center there is no curvature and so the ray does not bend. – Reid Erdwien Mar 20, 2015 at 7:07 2 The other rays bend towards the centre (or away from the centre in the concave case).
